EARTHWORKING- MACHINE.

Application filed December 12, 1922.

To all whom it may concern:

Be it known that I, JOAN JAcoB MARI ELIAS, a citizen of the Dutch East Indies, a resident of the city of Banjoemas, residency of Banjoemas, Isle of Java, have invented an Improved Earthworking Machine, of which the following is a full, clear, and exact specification.

My invention relates to an earthworking machine more particularly to be used in the sugar-cane culture.

The present invention is one of a series of inventions of mine which have for object to make it possible to carry outthe sugarcane-culture in an entirely mechanical way.

Reference is to be had to the accompanying drawings forming a part of this specification in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 a side-elevation and Figure 2 a plan view of the machine.

The machine is mounted on a motor-carriage-frame 1 of channel-iron which is moved on by the motor in any known manner as is shown schematically in dotted lines in Fig. 1.

Behind the seat of the driver of the carriage two bearings 2 and 3 are mounted, one behind the other on the carriage-frame. In the forward bearing 2 is adjustably guided in the vertical direction a frame carrying a left and a right plowshare 7 which frame comprises a horizontal bar 4, which can slide upward and downward in the bearing 2, and two vertical side-bars 5, which are guided in boxes 6 fixed to the carriage-frame and also supporting the bearing 2. The two shares 7 are arranged in reverse relation to each other, with their mold boards opposed. They serve to loosen or to break up the ground at both sides of the cane-clods and to throw the loosened ground up against the same,

By adjusting the depth-position of the two shares 7 the amount of earth that is thrown up can be regulated. This adjustment is performed by rotating a hand-wheel 9 which is fixed at the top of a screw-spindle 8 to which the frame 4, 5 is fixed.

Serial No. 606,471.

These rolls which are of the shape of truncated cones, press the thrown up soil aslant against the cane-clods so that long rigid walls are formed as is usual, from which the cane arises.

The rolls 10 are mounted on shafts carried by a frame which is adjustably mounted in the rear bearing 3, which frame comprises a horizontal bar 13 and two vertical side bars 11, from which the roll-shafts are extending sideways and which side-bars are guided in boxes 12 fixed to thecarriage-frame and supporting at the same time the bearing 3.

The depth-position of the two rolls 10 is adjustable. The horizontal frame-bar 18,

guided in the bearing 3, is suspended to a The wheel-shafts of the carriage are made.

in the form of a yoke with downward bent vertical side-pieces and with horizontal connecting middle-pieces at a height above the ground in order not to touch the tops of the sugar-cane plants.

The seat of the driver of the carriage is at the fore end, whilst the operator of the shares and rolls has his stand between the two bearings 2 and 3.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed I declare that what I claim is:

An earthworking machine, comprising two vertically adjustable plows arranged to throw the loosened earth inwardly between them and also arranged at a predetermined distance from each other, and two truncated conic rolls arranged in rear of the plows at about the same distance between them and with their smaller ends opposed and also vertically adjustable.

In testimony whereof, I have signed my name to this specification.
